Happy Pi Day!

Happy Pi Day! The Cuter & Shorter Half argues that today is 'Sundae', not 'Pie Day'.🤣 Of course, if like me, you use DD-MM-YY dating format, we also have 'Pi Approximation Day' on 22/7.

Some background on Pi Day. It is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant digits of π. UNESCO's 40th General Conference decided Pi Day as the International Day of Mathematics in November 2019.

Comments are subject to deletion if they are not germane. I have no problem with a bit of colourful language, but blasphemy or depraved profanity will not be allowed. Attacks on the Catholic Faith will not be tolerated. Comments will be deleted that are republican (Yanks! Note the lower case 'r'!), attacks on the legitimacy of Pope Francis as the Vicar of Christ (I know he's a material heretic and a Protector of Perverts, and I definitely want him gone yesterday! However, he is Pope, and I pray for him every day.), the legitimacy of the House of Windsor or of the claims of the Elder Line of the House of France, or attacks on the legitimacy of any of the currently ruling Houses of Europe.
